Filed: 1947-05-08
Abstract: 650,716. Casting moulds. RUBISSOW, G. A. May 8, 1947, No. 12500. [Class 87 (ii)] [Also in Group XXII] A mould is made by positioning a pattern within a casing, filling the. casing with the mould material, sawing the mould and embedded pattern into a number of parts, removing the separate parts of the pattern and then reassembling the mould parts to form a complete mould. The mould and pattern may be made of metals or alloys or of refractory material such as magnesium oxide, aluminium oxide, sand, bentonite, fire-clay, dolomite, talcum, graphite, cement either alone or mixed in powdered form with metals, natural or artificial rubber, mixtures of rubber with refractory materials, wood or cork, artificial plastics and resins including Lucite and materials known under the Registered Trade Marks " Bakelite " and " Cellophane," or of animal substances including shellac and solidified blood or of glass and various forms of silica. The pattern P may be supported within the casing by means of a runner pattern G and vent pattern V or by means of needle-like supports N<SP>1</SP>, N<SP>2</SP>, N<SP>3</SP>, N<SP>4</SP>, N<SP>5</SP>. Tubular members such as TM<SP>1</SP> and TM<SP>2</SP> may extend across the casing and after cutting the mould and removing the pattern they form holes for bolts B<SP>4</SP> and B<SP>9</SP> used for securing together the parts of the mould. A core such as K may be assembled with the mould parts. To compensate for the width of the saw cuts, either the pattern is made oversize or insertions such as IN<SP>1</SP>, IN<SP>2</SP> of a thickness approximating to the saw cuts are placed between the mould parts on assembly. In a modification, the mould material is first poured into the casing and the pattern is then thrust in before the material has solidified.

Title: Improvements in or relating to receivers for use in electric signalling systems
Inventor: BEET PHILIP HOWARD
IPC: H04B1/10
Filed: 1961-04-07
Abstract: 958,593. Radio Signalling. GENERAL ELECTRIC CO. Ltd. March 30, 1962 [April 7, 1961], No. 12589/61. Heading H4L. [Also in Division G4] The invention provides an apparatus for the reception of two or more pulse trains and for controlling a relay if the duration of reception is sufficiently long. In the embodiment described two interleaved pulse trains, comprising pulses of frequencies fa and fb respectively, are received by radio and detected at 3. Filters 4a, 4b separate the pulse trains, which are detected. The resultant D.C. pulses charge capacitors 16a, 16b. During reception the pulses produce a D.C. voltage on capacitor 9 of sufficient value to bias valves 21a, 21b to cut off. When reception ceases, and if both capacitors 16a and 16b have charged to a sufficiently high value (i.e. if the duration of reception has been sufficient), valves 21a, 21b will conduct and relays Pa, Pb will be energized. Capacitors 16a, 16b discharge slowly. Relays Pa, Pb control further relays Q and R, and hence S, so that contact Q2 is closed for a predetermined time, after which it opens and the apparatus is ready to receive the next pulse trains. The apparatus will not respond to continuous signals of frequencies fa and fb due to the presence of capacitors 17a, 17b. Further, it is necessary for both pulse trains to be present for relay Q to be operated. The invention may be extended for the reception of several pulse trains so that a number of relays may be selectively energized.

Abstract: 645,838. Storing and revaporizing gases. MINISTER OF SUPPLY. May 12, 1947, No. 12777. [Class 8(ii)] [Also in Group XXI] A method of discharging compressed carbon dioxide from a container 1 comprises injecting at high pressure hot combustion gases of a propellant 4 to the container 1 in the vicinity of its outlet 16; the resulting pressure rise on the surface of the liquefied carbon dioxide being transmitted by syphon effect through a column of liquid to rupture a disc 15, and the temperature rise serving to vaporize the liquefied carbon dioxide. The propellant, 4 is ignited on withdrawing a pin 5 which causes a striker 6 to ignite a cap and fuse 7 and a strip of impregnated cambric 17. The resulting hot gases burst a disc 10 which becomes impaled on a spike 13 and passes through eight passages 12 to the container neck. Should the pressure in the container 1 rise unduly it is vented to atmosphere through a spring-loaded non- return valve 22. The container is charged with liquid carbon dioxide through the duct 16 and three longitudinal ducts cut symetrically in the threads of a bush holding the disc 15, and which bush is screwed home on completion of the filling operation.
